ABSTRACT:
A signal processing apparatus includes a plurality of equalizer each used for a corresponding frequency band, controller for setting a gain value in each of the plurality of equalizer, and signal processor for processing an input signal by means of the plurality of equalizer. The controller determines a target gain value for each of the plurality of frequency bands, obtains a value of gain leakage from the first frequency band to a second frequency band adjacent to the first frequency band, updates a gain value set for the second frequency band, updates a gain value set for the first frequency band, repeats an update process for updating the gain value for each of the first frequency band and the second frequency band in an alternate manner until the gain value satisfies a predetermined condition, and sets the updated gain value for each of the frequency bands in the corresponding equalizer.
